WINDING MACHINE.

Application filed September 18, 1923. Serial No. 663,374.

T all w 710m it may concern Be it known that 1, MICHAEL LANDI, a

subject of the King of Italy, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Winding Machines, of which the following is a specification.

This invention relates to apparatus for winding thread or yarn of the class wherein the receiving element or spool rotates on a horizontal axis; more particularly, the invention relates to means for causing stop ping of the rotation of the receiving element or spool when a predetermined amount of yarn'has accumulated by causing the growing package to wipe against a contact device suitably placed to permit such wiping and thus act to shift said element clear of its rotary driver, such a means being set forth, for example, in my Patent No. 1,465,520, dated August 21, 1923. One object of the invention is to construct the stopping mechanism so that the stopping action will be quick and of definite duration in all cases and entirely independent for its celerity on the thickness of the material being wound, it being apparent upon reference to my said patented mechanism that the actual clearing of the receiving element from its driver in that case will take place a more or less length of time after its windings begin to wipe against the contact device according as the material being wound is thin or thick. Given a winding machine including a horizontal series of'rotary drivers. means to support series of rotary receiving elements in peripheral contact therewith so as to be driven thereby, and contact devices against wipe to cause shifting of the receiving elements away from their drivers. my invention further has for itsobject to arrange each contact device so as to be shiftable to positions where the corresponding growing mass of windings will contact therewith at any period in its development, and to combine with all such shiftable contact devices means for shifting them all atonce; thus the attendant can set the machine, by manipulating said means so that the winding as to every unit will be stopped when a predetermined yardage has accumulated.

In the drawing,

Fig. 1 is a fragmentary front elevation which the growing masses of winding may of a winding machine embodying my invenfor the spindles g of-the spools or receiving elements 72/ and guides f in which reciprocates the thread-guide or traverse rail 71. Each spindle, which has a whirl 9 adapted to bear peripherally on the corresponding driver 6, can be canted in its bearings f to clear its whirl from the driver, as usual.

The stopping mechanisms. one for each winding unit, are secured to the rails 6; a description of onewill serve for all:

A bracket 7' bears against the rails Z) and is held thereagainst by a clamping plate 70 through the medium of a screw Z and a nut The bracket is a vertically elongated strip with a cross-sectionally T-shaped groove y". In the groove is arranged the vertical. body portion of a strip n whose upper and lower ends are .bent outward. the former having an enlargement 71* and the latter having riveted thereto a fork. The support thus formed by the strip and fork is adapted to slide vertically in the bracket. The fork is formed from a suitably shaped blank having its arms or extremities a a bent up into parallelism with each other. These arms are formed with alined holes 0 and overlapping the hole of the arm n at its under side and removably secured to said arm is a knife p whose edge is up and so traverses the hole, while secured to the other arm n are an inclined guide or cam projecting outwardly therefrom and a light plate-spring '1' projecti ng inwardly therefrom. Fulcrumed on the arm n at the point 8 is a lever 6 arranged at the inner side of said arm; its rear end has a weight a which normally holds its forward end-portion'overlapping the hole 0 of said arm, the limit of movement of the lever underthe influence of its weight beingafiorded by an ear or lag? t at its forward end; engaging the under side of the arm. Loosely penetrating the holes 0 is the spindle of a roller 10 against which laterally bears the light spring '1'. The eX- tremity of the spindle which is received by the hole 0 in arm a is threaded, as at n, such threading being adapted to be engaged by the edge of knife 9; between this threaded portion and the roller the spindle has a reduced portion or neck a which preferably is joined with the threaded portion by a taper or conical shoulder a and which is engaged by the lever which, due to its weight. normally holds the spindle clear of the knife. The roller is positioned so as to underlie the corresponding spool or package of windings that is being formed when it is being rotated by its whirl resting in contact with the (going) driver.

In the normal position of the parts the rotary member formed by the spindle and roller (at that time not peripherally engaged by the package) is held to the right in Fig. 5 by spring 7", the weighted lever 25 as stated holding the right-hand or threaded end of the spindle elevated above and so unengaged by the knife p. When the package builds up sufficiently and so contacts with the roller it acts in the continued building thereof to depress the said rotary member against the pressure of the weighted lever until the threading of the spindle becomes engaged by the knife, where upon the rotary member formed by the spindle and roller, being kept in rotation by the package, is caused by such (screwthreaded) engagement with the knife to travel to the left. In doing so, the left hand end of the spindle rises along the camway or incline of the part (7, thus lifting the package clear of the driver, so that it stops rotating: due to cone w the lever 7 is readily cannned downward as the rotary member is shifted to the left. lhe rotary member remains in the position last assumed until the attendant; removes the package whereupon. the right-hand end of the spindle be ing now free to rise under the pressure of the weighted lever t, the said member clears the knife and under pressure of spring r is restored to its normal position. The stopping is performed quickly and in all cases (whether the yarn is coarse or fine) after the same lapse of time after the package begins to rotate said rotary member.

The mentioned support may be fixed to the bracket, if desired. in any way and so as to bring the rotary member more or less close to the package. as circumstances require. But I show all the supports movable in their brackets vertically and as having their enlargements received in the forks a2 projecting from a rock-shaft 7 which is journaled in the frame a and has at one end of the machine a handle 2 which moves with reference to a quadrant scale 2 on the frame. By this arrangement the attendant can set the machine so that the winding of the several packages will be stopped when a certain yardage has been attained, rotary adjUStIDQHlI of the shaft obviously resulting in setting the rotary members of the several strmping mechanisms toward or from the cor responding packages. Of course this part of my invention is not limited to any par- !iclular means whereby the spool is made to clear the driver due to its windings. in accumnlating, coming in contact with. some contact device.

The underlying principle of the specific mechanism herein shown and described for obtaining displacement of the package from the driver involves a rotary member, as rw, arranged in the supporting means so as to be revolved by the windings when they contact therewith and said means and member having means coacting on such r0- tation of said member to displace the lat ter lengthwise of its axis and crowd said member against the package, whereby to clear the latter from the driver; broadly the invention thus does not necessarily include the instrumentalities, such as 1" and t, which are present to cause resetting, automatically, of said rotary member each time it is thus displaced and upon removal of the filled spool.

Having thus fully described my invention. what I claim and desire to secure by Letters Patent is:

' 1. In combination, supporting means, a rotating driver journaled therein, a rotary element on which to wind the yarn and form the package journaled in the supporting means and normally urged into peripheral contact with the driver but yieldable therefrom. and a rotary member arranged in said supporting means at the side of the package adjoining the driver and adapted to be peripherally engaged and thereby rotated by the windings. said means and member having means coacting on rota tion of said member by the windings to displace said member lengthwise of its axis and crowd said member against the package.

2. In combination. supporting means, a rotating driver journaled therein. a rotary element on which to wind the yarn and form the package journaled in the supporting means and normally urged into periph eral contact with the driver but yieldable therefrom. and a rotary member arranged in said supporting means at the side of the package adioining the driver and adapted to be peripherally engaged and thereby rotated by the windings, said member being shiftable transversely of its axis by the windings on engagement thereof with and consequent rotation thereof by the windings and said means and member having means thereupon coaeting to displace said member lengthwise of its axis and thereby crowd said member against the package, yielding means to urge said member contrary to the direction in Which it is thus displaced, and yielding means to urge said member contrary to the direction in which it is shifted by the windings.

3. In combination, supporting means a plurality of alined rotary drivers journaled therein, a plurality of alined rotary elements on which to wind the yarns and form the packages journaled in the supporting means and. normall urged into contact With but yieldable from the respective drivers, con tact devices for the respective packages arranged each at the side of a package adjoining the corresponding driver and adapted to be engaged by the windings of said packages and means, movable in the supporting means, for adjusting the contact devices toward and from the packages in synchrony.

In testimony whereof I aliix my signature.

MICHAEL LANDI.
